Description

  The present invention relates to a curtain system, and more particularly to a curtain system having a damping force adjusting device.

  A conventional curtain has an upper beam, a shielding structure, a lower beam and a driving device. The shielding structure is located between the upper beam and the lower beam. The driving device is positioned on the upper beam and connected to the lower beam, thereby controlling the lower beam to be moved closer to or away from the upper beam and further to expand or close the shielding structure. However, in the process of deploying the shielding structure, the downward tensile force generated by the weight of the lower beam itself or the weight of the shielding structure gradually accelerates the rotational speed of the driving device, and further the curtain. This causes wear of the member or causes the lower beam to directly collide with an object located below the curtain.

  In view of the above problems, the present invention provides a curtain system that can reduce the deployment speed of the shielding structure. The curtain system of the present invention has a damping force adjusting device, which can increase the safety of use of the curtain system and reduce the wear of the curtain system member.

  The damping force adjusting device of the present invention is used to adjust the damping force when the curtain system is deployed, and includes a damping force output module and a damping force control module. The damping force output module includes a first damper member and a second damper member. When the first damper member and the second damper member move relative to each other, an interaction force is generated between the first damper member and the second damper member. Is generated, the damping force output module outputs a damping force to the curtain system, and the damping force control module is interlocked with the damping force output module, and when the first damper member and the second damper member perform relative motion, the damping force The control module changes the interaction force by changing the relative position between the first damper member and the second damper member, and changes the damping force output by the damping force output module.

  The curtain system of the present invention includes a shielding structure, a driving device for deploying or closing the shielding structure, and a damping force adjusting device connected to the driving device and including a damping force output module and a damping force control module. The damping force output module includes a first damper member and a second damper member. When the shielding structure is deployed, the damping force output module operates in conjunction with the driving device. The driving device includes the first damper member and the second damper member. By causing relative movement, an interaction force is generated between the first damper member and the second damper member, and the damping force output module outputs a damping force to the drive unit. The damping force control module is connected to the force output module and the driving device, and when the driving device relatively moves the first damper member and the second damper member, the damping force control module operates in conjunction with the driving device, so that the damping force control module is operated. Changes the relative position between the first damper member and the second damper member, changes the interaction force, and outputs a damping force output module to the drive device. To change the damping force.

  Compared to the prior art, the curtain system of the present invention can effectively control the speed of deployment of the shielding structure in the process of deployment of the shielding structure by the operation of the damping force adjusting device.

  The present invention will be described in detail in combination with the following specific embodiments and drawings.

  FIG. 1 is a diagram illustrating a state in which a curtain system 10 according to an embodiment of the present invention is closed. The curtain system 10 includes an upper beam 11, a lower beam 12, and an upper beam 11 and a lower beam 12. It includes an installed shielding structure 13. At this time, the shielding structure 13 is in a closed state, and the lower beam 12 is located at a high position (PH). FIG. 2 is a diagram showing a state in which the curtain system 10 is deployed, and a state in which the shielding structure 13 is also deployed. By extending downward from the upper beam 11, the lower beam 12 is lowered to a lower position (PL ).

  FIG. 3 is an exploded perspective view of the curtain system 10. The curtain system 10 further includes a control device 100, a driving device 200, and a damping force adjusting device 300. Both ends of the driving device 200 are connected to the control device 100 and the damping force adjustment device 300, respectively, but the connection relationship among the control device 100, the driving device 200, and the damping force adjustment device 300 is not limited thereto. That is, the control device 100, the driving device 200, and the damping force adjusting device 300 can be directly or indirectly connected to each other. Referring to FIG. 4, the control device 100 includes a lock release mechanism 110, and the lock release mechanism 110 and the drive device 200 are connected to each other. When the unlocking mechanism 110 is in a locked state, the driving device 200 can be prevented from being operated. Further, the user can operate the driving device 200 freely by releasing the lock of the unlocking mechanism 110 with respect to the driving device 200 and setting the unlocking mechanism 110 to the unlocked state. In FIG. 4, the control device 100 and its unlocking device 110 are similar to those described in US patent application Ser. No. 15 / 184,802, and in an embodiment of the present invention, the control device 100 and its unlocking device. Since the apparatus 110 is normally installed, it is not an important part in the present invention, and thus a detailed description thereof is omitted here. For a detailed description, please refer to the contents of the specification of the aforementioned U.S. patent application number.

  Referring to FIG. 3, one end of the lifting / lowering cord 14 is fixed to the lower beam 12, and the other end is connected to the driving device 200 via the shielding structure 13. In an embodiment of the present invention, the driving device 200 may include a winding shaft or a winding ring, and the lifting / lowering cord 14 may be wound around the driving device 200. Accordingly, in the embodiment of the present invention, after the unlocking mechanism 110 unlocks the driving device 200, the lower beam 12 is naturally linked to its own weight or the weight of the shielding structure 13 added thereto. While descending, the lifting / lowering cord 14 fixed to the lower beam 12 is pulled by the lower beam 12 to operate the driving device 200. In the embodiment of the present invention, the lifting / lowering cord 14 is pulled by the lower beam 12 to rotate the driving device 200. In the embodiment of the present invention, the driving device 200 may be a winding shaft, a winding ring, or a winding shaft.

  3 to 5, the driving device 200 is connected to the damping force adjusting device 300, and when the driving device 200 operates, the damping force adjusting device 300 outputs a damping force to the driving device 200. The operating speed of the driving device 200 is decreased. At the same time, the lowering speed of the lower beam 12 connected to the driving device 200 also decreases. Therefore, compared with the curtain system which does not have the damping force adjustment apparatus 300, the deployment speed of the shielding structure 13 in this invention is comparatively slow.

  However, the rotational speed of the driving device 200 or the moving speed of the lower beam 12 varies depending on the amount of damping force output from the damping force adjusting device 300. That is, as the damping force output from the damping force adjusting device 300 increases, the rotational speed of the driving device 200 and the deployment speed of the shielding structure 13 are slower. On the contrary, the amount of damping force output from the damping force adjusting device 300 Is smaller, the rotational speed of the driving device 200 and the deployment speed of the shielding structure 13 are faster. It should be particularly noted here that the damping force output from the damping force adjusting apparatus 300 of the present invention can be realized by different technical means. For example, a physical force capable of generating damping force such as magnetic force, frictional force, fluid viscous force or electrostatic force. It is realized by a damping force output module including a general force.

  2 and FIG. 3, taking the damping force adjusting device 300 shown in FIG. 5 as an example, the damping force adjusting device 300 includes a damping force output module 310 and a damping force control module 330, and the damping force output module. 310 and the damping force control module 330 are linked to each other. The damping force output module 310 includes a first damper member 312 and a second damper member 314. When the damping force output module 310 is operated, the first damper member 312 and the second damper member 314 move relative to each other, thereby generating an interaction force between the first damper member 312 and the second damper member 314. As a result, the damping force output module 310 outputs a damping force to the driving device 200 and acts on the deployment of the shielding structure 13 of the curtain system 10. On the other hand, since the damping force control module 330 is linked to the damping force output module 310, when the damping force output module 310 is operated, the damping force control module 330 is simultaneously operated, whereby the first damper member 312 and the first damper member 312 are operated. The relative position between the two damper members 314 is changed, the interaction force between the first damper member 312 and the second damper member 314 is changed, and the damping force output module 310 outputs to the driving device 200. Change power.

  In short, in the embodiment of the present invention, when the shielding structure 13 is deployed, the driving device 200 is operated to cause the damping force output module 310 to output a damping force to the driving device 200. When the driving device 200 continues to operate, the damping force control module 330 weakens the interaction force between the first damper member 312 and the second damper member 314 and provides a damping force output module to the driving device 200. The damping force output by 310 is reduced. In another embodiment of the present invention, the driving device is connected to the upper edge of the shielding structure, and the damping structure is deployed to actuate the driving device in conjunction with the damping force output module to attenuate the driving device. Force output. The damping force output from the damping force output module to the driving device by causing the damping force control module to increase the interaction force between the first damper member and the second damper member by continuously operating the driving device. Increase.

  As shown in FIGS. 5 and 6, the damping force control module 330 includes a moving mechanism 332. The moving mechanism 332 is connected to the first damper member 312 and moves the first damper member 312 in conjunction with it, thereby changing the relative position between the first damper member 312 and the second damper member 314. In the curtain system 10, the moving mechanism 332 further moves the first damper member 312 by interlocking with the driving device 200. Furthermore, the first damper member 312 is interlocked with the moving mechanism 332 and moves along the axial direction of the moving shaft 3324 of the moving mechanism 332, whereby the first damper member 312 and the second damper member 314 are moved. Change the relative position.

  Hereinafter, changes in the technical contents of the damping force adjusting devices 300, 400, and 500 and the connection relationship with various structures will be described in detail according to a plurality of embodiments of the present invention. In an embodiment of the present invention, the damping force control module can be simultaneously linked to the first damper member and the second damper member of the damping force output module, or can be linked only to the first damper member of the damping force output module.

  FIGS. 5-12 demonstrates the damping-force adjustment apparatus 300 of the Example of this invention. 5 to 7, the damping force adjusting device 300 includes a damping force output module 310 and a damping force control module 330, and the damping force output module 310 includes a first damper member 312 and a second damper member 314. The force control module 330 is simultaneously interlocked with the first damper member 312 and the second damper member 314 of the damping force output module 310.

  The damping force control module 330 includes a moving mechanism 332. The moving mechanism 332 includes a screw 3321 and a nut 3323 installed on the screw 3321. Since the first damper member 312 is installed on the nut 3323, when the screw 3321 rotates, the nut 3323 moves along the rotation axis direction of the screw 3321 in conjunction with the screw 3321, and at the same time, the nut 3323. The first damper member 312 that is installed in moves along the movement axis 3324. At this time, the moving shaft 3324 and the rotation axis direction of the screw 3321 are substantially parallel.

  The second damper member 314 of the damping force output module 310 has a rotation shaft 3141 and rotates about the rotation shaft 3141 as an axis. The rotating shaft 3141 of the second damper member 314 and the moving shaft 3324 of the moving mechanism 332 are substantially perpendicular. In the curtain system 10, the driving device 200 may further include a driving shaft, and the driving shaft and the moving shaft 3324 are substantially vertical. When the moving mechanism 332 is interlocked with the second damper member 314, the first damper member 312 is interlocked with the moving mechanism 332 and is displaced with respect to the second damper member 314, whereby the first damper member 312 and the second damper member 314 are displaced. The interaction force with the member 314 is changed. Specifically, the second damper member 314, the moving mechanism 332, and the driving device 200 are interlocked with each other. When the second damper member 314 is rotated in conjunction with the driving device 200, the first damper member 312 is interlocked with the moving mechanism 332. Then, it is displaced with respect to the second damper member 314, and the interaction force between the first damper member 312 and the second damper member 314 is changed.

  8 and 9, the first damper member 312 is a magnetic member 312a as an example, and the magnetic member 312a may be a magnet or an electromagnet. The second damper member 314 is exemplified by a conductor 314a, and the conductor 314a may be a disk made of a material capable of generating electromagnetic induction, such as an aluminum board or a copper board. When the magnetic member 312a and the conductor 314a perform relative motion, an electromagnetic induction acting force is generated between the magnetic member 312a and the conductor 314a, and the damping force control module 330 is connected between the magnetic member 312a and the conductor 314a. The electromagnetic induction acting force is changed by changing the relative position. It should be noted that the shapes and sizes of the magnetic member 312a and the conductor 314a are merely examples, and are not used to limit the scope of the present invention. In another embodiment of the present invention, the first damper member is the conductor, and the second damper member is the magnetic member.

  Referring to FIGS. 7, 8, and 9, the first damper member 312 is interlocked with the moving mechanism 332, and is displaced with respect to the radial direction of the rotation shaft 3141 of the second damper member 314. The interaction force between 312 and the second damper member 314 is changed. In FIG. 8, the magnetic member 312a is interlocked with the moving mechanism 332 and approaches the rotating shaft 3141 of the conductor 314a along the moving shaft 3324a. At this time, since the linear velocity of the conductor 314a with respect to the magnetic member 312a is reduced, the electromagnetic induction acting force generated between the conductor 314a and the magnetic member 312a becomes weak, and the damping force output module 310 outputs to the curtain system 10. The damping force is reduced. On the other hand, in FIG. 9, the magnetic member 312a is interlocked with the moving mechanism 332 and moves away from the rotating shaft 3141 of the conductor 314a along the moving shaft 3324a. At this time, the linear velocity of the conductor 314a with respect to the magnetic member 312a is accelerated, so that the electromagnetic induction acting force generated between the conductor 314a and the magnetic member 312a becomes strong. The damping force output from the damping force output module 310 to the curtain system 10 increases.

  Referring to FIGS. 7, 10, and 11, FIGS. 10 and 11 are other embodiments of the present invention, and there is an overlapping area between the first damper member 312 and the second damper member 314. The interaction force is generated in the overlapping area between the first damper member 312 and the second damper member 314. Since the second damper member 314 is interlocked with the movement mechanism 332, when the second damper member 314 rotates about the rotation shaft 3141, the movement mechanism 332 is connected to the first damper member 312 and the second damper member 314. The overlapping area is changed, and the interaction force between the first damper member 312 and the second damper member 314 is changed. The first damper member 312 may be a magnetic member 312b, and the second damper member 314 may be a conductor 314a. It should be noted here that the shapes and sizes of the magnetic member 312b and the conductor 314a are merely examples, and are not used to limit the scope of the present invention. In FIG. 10, the moving mechanism 332 moves the magnetic member 312b along the moving shaft 3324b, and at this time, the overlapping area 3121 of the electromagnetic induction acting force that can be generated between the conductor 314a and the magnetic member 312b is reduced. The electromagnetic induction acting force generated between the conductor 314a and the magnetic member 312b is weakened. Accordingly, the damping force output from the damping force output module 310 to the curtain system 10 decreases. On the contrary, in FIG. 11, the moving mechanism 332 moves the magnetic member 312b along the moving shaft 3324b, and at this time, an overlapping area 3121 where an electromagnetic induction acting force can be generated between the conductor 314a and the magnetic member 312b. Increases, the electromagnetic induction acting force generated between the conductor 314a and the magnetic member 312b becomes stronger. As a result, the damping force output from the damping force output module 310 to the curtain system 10 increases.

  It should be noted that FIGS. 8 to 11 illustrate the effect of continuously changing the damping force provided by the damping force adjusting device 300 according to the embodiment of the present invention, taking the magnetic damping force as an example. Yes, it is not used to limit the embodiment of the damping force adjusting device 300. In other embodiments of the present invention, the damping force adjustment device 300 may be damped by other types of damping forces that are still optimal and reasonable, such as friction damping forces, oil damping forces, or electrostatic damping forces. It can also provide power. In addition, by simultaneously installing a plurality of types of damping force output modules in a single damping force adjusting device, the effect of the damping force provided by the damping force adjusting device on the curtain system can be improved.

  Referring to FIGS. 6 and 7, the damping force control module 330 is further interlocked simultaneously with the first damper member 312 and the second damper member 314 in the damping force output module 310 by the interlocking rod 334. Specifically, the interlocking rod 334 includes a bevel gear 3341, a spur gear 3343, and a rod body 3345, and a bevel gear 3341 and a spur gear 3343 are installed on both ends of the rod body 3345, respectively.

  The moving mechanism 332 also has a bevel gear 3325 installed at one end of the screw 3321. Since the bevel gear 3341 of the interlocking rod 334 and the bevel gear 3325 of the moving mechanism 332 mesh with each other, when the interlocking rod 334 rotates, the screw 3321 of the moving mechanism 332 rotates in conjunction with the interlocking rod 334, and further, the nut 3323 and the The position of one damper member 312 is moved. That is, the relative position of the first damper member 312 and the second damper member 314 is changed. In the embodiment of the present invention, the rod 3345 of the interlocking rod 334 and the screw 3321 of the moving mechanism 332 are substantially vertical, but are not limited thereto.

  The damping force output module 310 further includes a spur gear 202 that is coaxially installed and connected to the second damper member 314. Since the spur gear 3343 of the interlocking rod 334 is interlocked with the spur gear 202 of the damping force output module 310, when the spur gear 202 rotates, the interlocking rod 334 rotates in conjunction with the spur gear 202 and simultaneously, the spur gear 202 is rotated. The second damper member 314 installed coaxially with the spur gear 202 rotates in conjunction with the spur gear 202. In the embodiment of the present invention, the interlocking rod 334 and the rotation shaft 3141 of the second damper member 314 are substantially parallel. It should be noted that in the embodiment of the present invention, the driving device 200 of the curtain system 10 is connected to and interlocked with the damping force adjusting device 300 by the spur gear 202, and the driving device 200 is connected to the damping force output module 310. The two damper members 314 are installed on the same axis. In another embodiment of the present invention, the rotating shaft of the driving device can be substantially parallel or perpendicular to the rotating shaft of the second damper member, or the rotating shaft of the driving device is installed coaxially with the interlocking rod. You can also.

  The curtain system 10 can further include an acceleration structure 370. The acceleration structure 370 is linked to the driving device 200 and the damping force output module 310 and is installed between the driving device 200 and the damping force output module 310. Specifically, the acceleration structure 370 is installed between the second damper member 314 of the damping force output module 310 and the spur gear 202. When the driving device 200 is operated, the acceleration structure 370 is operated in conjunction with the driving device 200. In this case, the acceleration structure 370 determines the speed of relative motion between the first damper member 312 and the second damper member 314. The operating speed of the driving device 200 is made faster. More specifically, when the acceleration structure 370 operates, the second damper member 314 is linked to the acceleration structure 370 to accelerate the rotation speed, thereby generating between the first damper member 312 and the second damper member 314. The interaction force is increased, and the damping force output from the damping force output module 310 to the drive device 200 is increased. In an embodiment of the present invention, the acceleration structure 370 may be a planetary gear acceleration structure or other acceleration device having a similar effect. Note that if the curtain system 10 does not include the acceleration structure 370 and the damping force output module 310 can output a sufficient damping force to the curtain system 10, an extra acceleration structure 370 is installed in the curtain system 10. do not have to. In other words, whether or not the acceleration structure 370 is additionally installed in the curtain system 10 can be determined according to the output state of the actual damping force. Therefore, the acceleration structure 370 is the curtain system according to the embodiment of the present invention. 10 is not a necessary member.

  Referring to FIGS. 6, 7, and 12, the curtain system 10 further includes a unidirectional control structure 350, which is connected to the drive device 200 and the damping force output module 310 and is connected to the drive device 200. And the damping force output module 310. In an embodiment of the present invention, the unidirectional control structure 350 may be a roller clutch, a spring clutch, a track clutch, a friction clutch, a ratchet clutch, or other unidirectional clutch having similar effects. When the shielding structure 13 is deployed, the driving device 200 rotates the unidirectional control structure 350 in the first direction D1 and relatively moves the first damper member 312 and the second damper member 314, thereby reducing the damping force. The output module 310 is caused to output a damping force to the driving device 200. On the contrary, when closing the shielding structure 13, the driving device 200 rotates in the second direction D2, which is the opposite direction to the first direction D1, and the unidirectional control structure 350 causes the driving device 200 to move to the damping force output module. Independently from 310, it is freely rotated in the second direction D2. In other words, when closing the shielding structure 13, the driving device 200 rotates in the second direction D <b> 2, and at this time, the unidirectional control structure 350 stops the interlocking between the damping force output module 310 and the driving device 200. As a result, the damping force output module 310 stops outputting the damping force to the drive device 200. It should be noted here that when the driving device 200 rotates in the second direction D2, the unidirectional control structure 350 stops the linkage between the damping force output module 310 and the driving device 200, but the driving device 200 is still damped. Since the interlocking with the force control module 330 is maintained, the rotation of the driving device 200 operates the damping force control module 330 in conjunction with the first damper member 312 connected to the moving mechanism 332 so that the shielding structure 13 Return to the closed position. However, in the embodiment of the present invention, the unidirectional control structure 350 is normally installed, and thus is not an important part in the present invention, and thus detailed description thereof will be omitted.

  FIGS. 13 to 15 illustrate a damping force adjusting device 400 according to an embodiment of the present invention. 13 and 14, the damping force adjusting device 400 includes a damping force output module 410 and a damping force control module 430, and the damping force output module 410 includes a first damper member 412 and a second damper member 414. The damping force control module 430 operates simultaneously with the first damper member 412 and the second damper member 414 in the damping force output module 410.

  The damping force control module 430 includes a moving mechanism 432. The moving mechanism 432 includes a screw 4321 and a nut 4323 installed on the screw 4321. Since the first damper member 412 is connected to the nut 4323, when the screw 4321 rotates, the nut 4323 is interlocked with the screw 4321 and moves along the rotational axis direction of the screw 4321, and at the same time connected to the nut 4323. The first damper member 412 is moved along the movement axis 4324. The moving shaft 4324 and the rotation axis direction of the screw 4321 are substantially parallel. In the embodiment of the present invention, the first damper member 412 and the nut 4323 are integrally formed, or the first damper member 412 is installed on the nut 4323. In the curtain system 10, the driving device 200 has a driving shaft, and the driving shaft and the moving shaft 4324 of the moving mechanism 432 are substantially parallel to each other.

  The second damper member 414 of the damping force output module 410 has a rotation shaft 4141 and rotates around the rotation shaft 4141. The rotating shaft 4141 of the second damper member 414 is installed coaxially with the moving shaft 4324 of the moving mechanism 432. When the moving mechanism 432 is interlocked with the second damper member 414, the first damper member 412 is interlocked with the moving mechanism 432 and displaced with respect to the second damper member 414, so that the first damper member 412 and the second damper member are connected. The interaction force with 414 is changed. More specifically, since the second damper member 414, the moving mechanism 432, and the driving device 200 are interlocked with each other, the first damper member 412 is moved by the moving mechanism 432 when the second damper member 414 rotates in conjunction with the driving device 200. Are displaced with respect to the second damper member 414, and the interaction force between the first damper member 412 and the second damper member 414 is changed. More specifically, the first damper member 412 is interlocked with the moving mechanism 432 and relatively displaced along the axial direction of the rotation shaft 4141 of the second damper member 414, thereby the first damper member 412 and the second damper member. The interaction force with 414 is changed.

  Next, referring to FIGS. 13 to 15, the first damper member 412 is exemplified by a hollow sleeve, a part of the inner wall 4121 of the hollow sleeve is substantially conical, and the second damper member 414 is exemplified by an elastic body, It may be an elastic body that is substantially S-shaped or Z-shaped or another elastic body having the same effect. The elastic body of the second damper member 414 contacts the inner wall 4121 of the first damper member 412. The elastic body has a rotation shaft 4141. The elastic body rotates around the rotation shaft 4141 as an elastic body. Frictional force is generated between the inner wall 4121 and the inner wall 4121. More specifically, when the elastic body rotates, the elastic body extends in the radial direction of the rotating shaft 4141 by centrifugal force to contact the inner wall 4121 and further generate the frictional force. It should be noted here that the shapes and sizes of the first damper member 412 and the second damper member 414 in FIGS. 13 to 16 are merely examples, and are not used to limit the scope of the present invention. In another embodiment of the present invention, the first damper member is the elastic body, and the second damper member is the hollow sleeve.

  In FIG. 13, the moving mechanism 432 moves the first damper member 412 in conjunction with the moving shaft 4324, and when the first damper member 412 approaches the second damper member 414, the inner wall of the first damper member 412 is moved. The inner diameter of 4121 is reduced and the substantially S-shaped second damper member 414 is pushed to increase the frictional force between the first damper member 412 and the second damper member 414. Thereby, the damping force output from the damping force output module 410 to the curtain system 10 increases. On the contrary, when the first damper member 412 moves away from the second damper member 414, the inner diameter of the inner wall 4121 of the first damper member 412 increases, and the second damper member 414, which is substantially S-shaped, is loosened. The frictional force between the first damper member 412 and the second damper member 414 is weakened. Thereby, the damping force output from the damping force output module 410 to the curtain system 10 is reduced. In the embodiment of the present invention, when the damping force control module 430 changes the relative position between the first damper member 412 and the second damper member 414, the inner wall 4121 of the first damper member 412 is The frictional force is changed by changing the length in the radial direction.

  However, in another embodiment of the present invention, when the first damper member moves away from the second damper member, the inner diameter of the inner wall of the first damper member is reduced, and the second damper member having a substantially S shape is pushed, The frictional force between the damper member and the second damper member is increased. As a result, the damping force output from the damping force output module to the curtain system increases. On the contrary, when the first damper member approaches the second damper member, the inner diameter of the inner wall of the first damper member is increased, the second S-shaped second damper member is loosened, and the first damper member and the first damper member are Reduce the frictional force between the two damper members. As a result, the damping force output from the damping force output module to the curtain system is reduced. In another embodiment of the present invention, if it is necessary to increase and decrease the output of the damping force that continuously changes in accordance with the deployment process in the process of deploying the shielding structure, The inner diameter of the inner wall of the first damper member can be changed corresponding to the damping force required in the process of developing the structure, for example, the inner diameter of the inner wall of the first damper member can be changed in a wave shape. .

  It should be noted that FIGS. 13 to 15 illustrate the effect of continuously changing the damping force provided by the damping force adjusting device 400 according to the embodiment of the present invention, taking the damping force due to friction as an example. However, it is not used to limit the embodiment of the damping force adjusting device 400. In other embodiments of the present invention, the damping force adjustment device 400 may provide damping force with other types of damping forces that are still optimal and reasonable, such as magnetic damping forces, oil damping forces, or electrostatic damping forces. It can also be provided. Also, by installing a plurality of types of damping force output modules at the same time in a single damping force adjusting device, the effect of the damping force provided by the damping force adjusting device on the curtain system can be improved.

  Referring to FIGS. 13 and 14, the damping force control module 430 further interlocks simultaneously with the first damper member 412 and the second damper member 414 in the damping force output module 410 via the interlocking rod 434.

  The moving mechanism 432 also has a spur gear 4325 installed at one end of the screw 4321. Unlike the bevel gear used in the above embodiment, the interlocking rod 434 meshes with the spur gear 4325 of the moving mechanism 432 by the spur gear 4341. Therefore, when the interlocking rod 434 rotates, the screw 4321 of the moving mechanism 432 is It rotates in conjunction with the interlocking rod 434 and further moves the positions of the nut 4323 and the first damper member 412. In the embodiment of the present invention, the rod body 4345 of the interlocking rod 434 and the screw 4321 of the moving mechanism 432 are substantially parallel, but are not limited thereto.

  The damping force output module 410 further includes a spur gear 202 that is coaxially installed and connected to the second damper member 414. Since the spur gear 4343 of the interlocking rod 434 is interlocked with the spur gear 202 of the damping force output module 410, when the spur gear 202 rotates, the spur gear 202 rotates in conjunction with the interlocking rod 434 and at the same time, the spur gear 202 is rotated. The second damper member 414 installed coaxially with the spur gear 202 rotates in conjunction with the spur gear 202. In the embodiment of the present invention, the interlocking rod 434 and the rotation shaft 4141 of the second damper member 414 are substantially parallel. It should be noted that in the embodiment of the present invention, the driving device 200 of the curtain system 10 is connected and interlocked with the damping force adjusting device 400 by the spur gear 202, and the driving device 200 is connected to the damping force output module 410. The two damper members 414 are installed on the same axis.

  3 and 14, the curtain system 10 may further include an acceleration structure 370, which is linked to the driving device 200 and the damping force output module 410, and includes the driving device 200 and the damping force output module 410. It is installed between. Specifically, the acceleration structure 370 is installed between the second damper member 414 of the damping force output module 410 and the spur gear 202. The accelerating structure 370 is not a necessary member in the curtain system 10 according to the embodiment of the present invention, and the installation conditions, purpose, and effect of the accelerating structure 370 are all described in detail in the above description. Description is omitted.

  Referring to FIGS. 3 and 14, the curtain system 10 further includes a unidirectional control structure 350, which is connected to the drive device 200 and the damping force output module 410, and the drive device 200 and the damping force output. It is installed between the module 410. In the embodiment of the present invention, since the unidirectional control structure 350 is normally installed, it is not an important part in the present invention, and the installation conditions, purpose and effect of the unidirectional control structure 350 are already present. Since it explained in detail in the above-mentioned contents, explanation here is omitted.

  16 to 26 illustrate a damping force adjusting device 500 according to an embodiment of the present invention. 16 to 26, the damping force adjusting device 500 includes a damping force output module 510a and a damping force control module 530, and the damping force output module 510a includes a first damper member 512a and a second damper member 514a. The damping force control module 530 works only with the first damper member 512a of the damping force output module 510a.

  Referring to FIGS. 16 to 18, the damping force control module 530 includes a moving mechanism 532, and the first damper member 512 a rotates simultaneously with the moving shaft 5325 as an axis in conjunction with the moving mechanism 532. Specifically, the moving mechanism 532 includes a screw 5321, a bushing 5323, and a base 5326. One end of the screw 5321 is inserted into the bushing 5323, and the bushing 5323 is fixed to the base 5326. The outer thread 5322 of the screw 5321 is screwed with the inner thread 5324 of the bushing 5323. Since the bushing 5323 is fixed to the base 5326, the screw 5321 moves along the axial direction of the moving shaft 5325 when the screw 5321 rotates. On the other hand, the first damper member 512a of the damping force output module 510a is connected to the other end of the screw 5321. When the screw 5321 rotates, the first damper member 512a rotates in conjunction with the screw 5321. In the embodiment of the present invention, the moving shaft 5325, the rotating shaft of the screw 5321 and the rotating shaft 5122a of the first damper member 512a are coaxially installed. In another embodiment of the present invention, the moving shaft 5325, the rotating shaft of the screw 5321, and the rotating shaft 5122a of the first damper member 512a may be installed in parallel, coaxially, or a combination of the two. In the curtain system 10, the driving device 200 has a driving shaft, which is installed coaxially with the moving shaft 5325 of the moving mechanism 532, and the driving device 200 interlocks with the moving mechanism 532, and the moving mechanism 532. Interlocks with the first damper member 512a, and the first damper member 512a rotates about the moving shaft 5325 as an axis.

  The first damper member 512a of the damping force output module 510a is inserted into the second damper member 514a, and the first damper member 512a is installed between the moving mechanism 532 and the second damper member 514a. Furthermore, the moving mechanism 532 is installed between the second damper member 514a and the driving device 200. When the moving mechanism 532 is operated, the first damper member 512a is interlocked with the moving mechanism 532, and is displaced with respect to the second damper member 514a, whereby the mutual between the first damper member 512a and the second damper member 514a. Change the acting force. Specifically, when the screw 5321 of the moving mechanism 532 rotates, the screw 5321 moves along the axial direction of the moving shaft 5325 and simultaneously moves along the axial direction of the moving shaft 5325 in conjunction with the first damper member 512a. And the first damper member 512a is displaced with respect to the second damper member 514a, and the interaction force between the first damper member 512a and the second damper member 514a is changed.

  Next, referring to FIG. 19 to FIG. 21, the first damper member 512a is an elastic body, and this elastic body includes an elastic member 5121a, a friction element 5123a, and a mounting table 5125a, and the elastic member 5121a and the friction element 5123a are The elastic member 5121a and the friction element 5123a are both connected to each other and placed on the mounting table 5125a. The second damper member 514a is exemplified by a hollow sleeve, and a part of the inner wall 5141a of the hollow sleeve is substantially conical. The elastic body of the first damper member 512a is in contact with the inner wall 5141a of the second damper member 514a, and the elastic body has a rotation shaft 5122a. The elastic body generates a frictional force between the elastic body and the inner wall 5141a by rotating about the rotation shaft 5122a. In FIG. 19, the elastic member 5121a is installed through the mounting table 5125a, and the two friction elements 5123a are installed at both ends of the elastic member 5125a, so that the two friction elements 5123a are installed symmetrically with each other. . In FIG. 20, one end of the elastic member 5121a is fixed to the mounting table 5125a, and the other end of the elastic member 5121a is connected to the friction element 5123a, so that the friction element 5123a is installed asymmetrically. It should be noted here that the shapes and sizes of the elastic member 5121a, the friction element 5123a, the mounting table 5125a, and the inner wall 5141a of the hollow sleeve are merely examples, and are not used to limit the scope of the present invention. In another embodiment of the present invention, the first damper member is the hollow sleeve, and the second damper member is the elastic body.

  Referring to FIG. 17, the moving mechanism 532 moves the first damper member 512a along the moving shaft 5325 in conjunction with the second damper member 514a when the first damper member 512a approaches the second damper member 514a. The inner diameter of the inner wall 5141a is reduced, and the friction element 5123a of the first damper member 512a is pushed to shorten the distance between the two friction elements 5123a. That is, the length of the elastic body with respect to the radial direction of the rotating shaft 5122a is shortened. At this time, since the frictional force between the first damper member 512a and the second damper member 514a becomes strong, the damping force output from the damping force output module 510a to the curtain system 10 increases. On the contrary, when the second damper member 514a moves away from the first damper member 512a, the inner diameter of the inner wall 5141a of the second damper member 514a is increased, the friction element 5123a of the first damper member 512a is loosened, and the two The distance between the friction elements 5123a is increased. That is, the length of the elastic body with respect to the radial direction of the rotating shaft 5122a is increased. At this time, since the frictional force between the first damper member 512a and the second damper member 514a becomes weak, the damping force output from the damping force output module 510a to the curtain system 10 decreases.

  However, in another embodiment of the present invention, when the first damper member moves away from the second damper member, the inner diameter of the inner wall of the second damper member is reduced, and the friction member of the first damper member is pushed to Reduce the distance between the children. At this time, since the frictional force between the first damper member and the second damper member becomes strong, the damping force output from the damping force output module to the curtain system increases. On the contrary, when the second damper member approaches the first damper member, the inner diameter of the inner wall of the second damper member is increased, thereby loosening the friction of the first damper member, and Increase the distance between. At this time, since the frictional force between the first damper member and the second damper member becomes weak, the damping force output from the damping force output module to the curtain system decreases. In another embodiment of the present invention, if it is necessary to increase and decrease the output of the damping force that continuously changes in accordance with the deployment process in the process of deploying the shielding structure, The inner diameter of the inner wall of the second damper member can be changed in response to the damping force required for the stroke in which the structure is deployed, for example, the inner diameter of the inner wall of the second damper member can be changed in a wave shape. .

  22 to 26 illustrate another embodiment of the damping force adjusting device 500 in the embodiment of the present invention. The damping force adjusting device 500 includes a damping force output module 510b and a damping force control module 530, and the damping force output module 510b includes a first damper member 512b and a second damper member 514b. The damping force control module 530 works only with the first damper member 512b of the damping force output module 510b. Although the damping force control module 530 includes a moving mechanism 532, the composition structure of the moving mechanism 532 and the connection relationship between the members have already been described in detail in the contents in FIGS. Description is omitted.

  The first damper member 512b of the damping force output module 510b is inserted into the second damper member 514b, and the first damper member 512b is installed between the moving mechanism 532 and the second damper member 514b. When the movement mechanism 532 is operated, the first damper member 512b is interlocked with the movement mechanism 532, and is displaced with respect to the second damper member 514b, whereby the mutual between the first damper member 512b and the second damper member 514b. Change the acting force. 18 and 23, when the screw 5321 of the moving mechanism 532 rotates, the screw 5321 moves along the axial direction of the moving shaft 5325, and at the same time, the first damper member 512b is interlocked with the moving shaft 5325. The first damper member 512b is displaced with respect to the second damper member 514b, and the interaction force between the first damper member 512b and the second damper member 514b is changed.

  Next, referring to FIG. 23 to FIG. 26, the first damper member 512b has a substantially cylindrical appearance, and includes one or more concentric circular structures 5123b and an accommodation space 5121b. A part is partitioned by a concentric circular structure 5123b. The second damper member 514b has an internal structure similar to that of the first damper member 512b, and includes one or more concentric structures 5143b and an accommodating space 5141b. A part of the accommodating space 5141b is partitioned by the concentric structure 5143b. It has been. It should be noted here that since the inner diameter of the accommodation space 5141b of the second damper member 514b is larger than the outer diameter of the first damper member 512b, the first damper member 512b is accommodated in the accommodation space 5141b of the second damper member 514b. And can move in the space. In the embodiment of the present invention, the first damper member 512b is completely or partially accommodated in the accommodation space 5141b of the second damper member 514b. In another embodiment of the present invention, the first damper member and the second damper member may independently include a disturbance device, such as a fan blade or a paddle, that generates a drag force by disturbing another fluid. it can.

  Further, fluid exists between the first damper member 512b and the second damper member 514b, and the interaction force generated between the first damper member 512b and the second damper member 514b is fluid resistance. In an embodiment of the present invention, the fluid includes a liquid or a gas, and particularly refers to a grease having a high viscosity, such as a damper oil. 25 and 26, the fluid fills the accommodation space 5141b of the second damper member 514b. Specifically, the fluid fills the sealed space formed by the bushing 5323 and the second damper member 514b. In order to prevent fluid from flowing out of the bushing 5323, the damping force control module 530 further includes a sealing ring 534, and a screw 5321 is inserted into the sealing ring 534. The sealing ring 534 is positioned between the screw 5321 and the bushing 5323 to enhance the sealing capability of the damping force control module 530.

  25 and 26, there is an overlapping area between the first damper member 512b and the second damper member 514b, and the fluid resistance is an overlapping area between the first damper member 512b and the second damper member 514b. Occurs. When the first damper member 512b and the second damper member 514b perform relative movement, a fluid resistance is generated between the first damper member 512b and the second damper member 514b and the fluid. At this time, the damping force control module 530 is generated. Changes the overlapping area between the first damper member 512b and the second damper member 514b by changing the relative position between the first damper member 512b and the second damper member 514b. This overlapping area changes the fluid resistance by generating a fluid resistance between the first damper member 512b and the second damper member 514b. In other words, when the screw 5321 of the moving mechanism 532 rotates, the screw 5321 moves along the axial direction of the moving shaft 5325 and simultaneously moves along the axial direction of the moving shaft 5325 in conjunction with the first damper member 512b. By doing so, the overlapping area where fluid resistance can be generated between the first damper member 512b and the second damper member 514b is changed. Referring to FIG. 25, when the first damper member 512b approaches the bushing 5323 along the movement axis 5325, the movement between the concentric structure 5123b of the first damper member 512b and the concentric structure 5143b of the second damper member 514b. The overlapping area of the shaft 5325 in the radial direction (the portion between the dotted lines L1 and L2) decreases, weakens the fluid resistance generated, and further reduces the damping force output by the damping force output device 510b. On the contrary, referring to FIG. 26, when the first damper member 512b moves away from the bushing 5323 along the moving shaft 5325, the concentric structure 5123b of the first damper member 512b and the concentric structure 5143b of the second damper member 514b , The overlapping area in the radial direction of the moving shaft 5325 (portion between the dotted lines L3 and L4) is increased, and the generated fluid resistance is increased, and the damping force output from the damping force output device 510b is increased.

  23, 25, and 26, when the first damper member 512b moves into the second damper member 514b, the fluid passes through the communication path 5145b in the second damper member 514b. And the space B, whereby the state in which the fluid is filled in the accommodation space 5141b of the second damper member 514b is maintained. In another embodiment of the present invention, the second damper member does not have a communication path, but a gas is introduced or exhausted due to a vent hole at the top of the accommodation space of the second damper member. The contact area with the one damper member changes based on the stroke in which the shielding structure is deployed, and further changes the damping force output from the damping force output module to the drive device. This is an embodiment in which other damping forces change continuously.

  Here, it should be noted that FIGS. 16 to 26 are examples of a damping force caused by friction and a damping force caused by oil, respectively, and are provided by the damping force adjusting device 500 according to the embodiment of the present invention. It is intended to explain the changing effect and is not used to limit the embodiment of the damping force adjusting device 500. In other embodiments of the present invention, the damping force adjustment device 500 can still be represented by other types of damping forces that are optimal and reasonable, such as magnetic damping forces or electrostatic damping forces. In addition, by simultaneously installing a plurality of types of damping force output modules in a single damping force adjusting device, the effect of the damping force provided by the damping force adjusting device on the curtain system can be improved.

  3, 17, and 23, the curtain system 10 further includes a unidirectional control structure 350, which is connected to the drive device 200 and damping force output modules 510a, 510b, and the drive device. 200 and the damping force output modules 510a and 510b.
